The recursive call chain dsl_scan_visitbp() -> dsl_scan_recurse() -> dsl_scan_visitdnode() -> dsl_scan_visitbp has been observed to consume considerable stack resulting in a stack overflow (>8k). The cleanest way I see to fix this with minimal impact to the existing flow of code, and with the fewest performance concerns, is to always inline dsl_scan_recurse() and dsl_scan_visitdnode(). While this will increase the function size of dsl_scan_visitbp(), by 4660 bytes, it also reduces the stack requirements by removing the function call overhead. Issue #174
Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
$ ./configure
$ make pkg
